Yes, that should be possible, even i never used that. So, you want a
first come first get policy ?

There is no nice api for detecting the number of processes in a group
but i will add one as i think it's a valid decision to consider. There
is no per se limit of processes in a group, in fact: there is no way to
limit processes numbers anyhow, unfortunately. Makes it very hard to
write write a fork bomb protector ;-)

But, you can of course just stop moving processes into a group.

Yesterday i added a instant filter functionality that allows you with
witelists to move processes extremly quickly. This is required for some
daemons that request realtime and then messure the cpu time they get to
test if it's enough for running smoothly. Those problematic processes
must be whitelisted because the normal delay mechanism would schedule
them to late, as many processes started are just short running and
looking at them is just a waste of cpu time.

kind regards
Daniel
